Problem |
Find the greatest common factor 42 and 49. |
|
2 |
Hint |
Finding the greatest common factor (GCF) of two numbers involves determining the largest number that divides both numbers without leaving a remainder. |
|
3 |
Step |
Let’s find the GCF of 42 and 49 using a step-by-step process: |
|
4 |
Step |
Factors of 42: |
1, 2, 3, 6, 7, 14, 21, 42 |
5 |
Step |
Factors of 49: |
1, 7, 49 |
6 |
Step |
Common factors of 42 and 49 are |
1,7 |
7 |
Step |
The greatest common factor (GCF) of 42 and 49 is 7, as it’s the largest number that divides both 42 and 49 without leaving a remainder. |
|
8 |
Step |
So, the greatest common factor of 42 and 49 is |
7 |

Sumup |
Can you summarize what you’ve understood in the above steps? |
|
10 |
Choice.A |
The GCF of 42 and 49 is the highest number that can divide both without leaving a remainder so this is correct |
7 |
11 |
Choice.B |
This is not correct. While 3 is a factor of 42, it is not a factor of 49. The greatest common factor must be a factor of both numbers |
3 |
12 |
Choice.C |
This is not correct because 5 is not a factor of either 42 or 49 in this case |
5 |
13 |
Choice.D |
This is not correct. 1 is a common factor of all numbers, but it is not the greatest common factor in this case |
